Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pages: 167. Not illustrated. Chapters: Cobalt-60, Cobalt-59, Cobalt-57, Cobalt-56, Cobalt-58m1, Cobalt-58m2, Cobalt-66m1, Cobalt-66m2, Cobalt-52m, Cobalt-53m, Cobalt-54m, Cobalt-60m, Cobalt-62m, Cobalt-68m, Cobalt-70m, Cobalt-47, Cobalt-48, Cobalt-49, Cobalt-50, Cobalt-51, Cobalt-55, Cobalt-71, Cobalt-72, Cobalt-73, Cobalt-74, Cobalt-75, Cobalt-69, Cobalt-61, Cobalt-63, Cobalt-64, Cobalt-65, Cobalt-67. Excerpt: Naturally occurring cobalt (Co) is composed of 1 stable isotope, Co. 22 radioisotopes have been characterized with the most stable being Co with a half-life of 5.2714 years, Co with a half-life of 271.79 days, Co with a half-life of 77.27 days, and Co with a half-life of 70.86 days. All of the remaining radioactive isotopes have half-lives that are less than 18 hours and the majority of these have half-lives that are less than 1 second. This element also has 4 meta states, all of which have half-lives less than 15 minutes. The isotopes of cobalt range in atomic weight from 50 u (Co) to 73 u (Co). The primary decay mode for isotopes with atomic mass unit values less than that of the most abundant stable isotope, Co, is electron capture and the primary mode of decay for those of greater than 59 atomic mass units is beta decay. The primary decay products before Co are element 26 (iron) isotopes and the primary products after are element 28 (nickel) isotopes. Standard atomic mass: 58.933195(5) u Cobalt-60 (Co-60 or Co) is a radioactive metal that is used in radiotherapy. It produces two gamma rays with energies of 1.17 MeV and 1.33 MeV. The Co source is about 2 cm in diameter and as a result produces a geometric penumbra, making the edge of the radiation field fuzzy. The metal has the unfortunate habit of producing a fine dust, causing problems with radiation protection. The Co source is useful for about 5 years but even after this p...
